“This storm is wider than our entire state and is expected to cause major and life-threatening impacts from coast to coast,” Scott said. “Regardless of which coast you live on, be prepared to evacuate.”

Scott has ordered mandatory evacuations in Monroe County, the location of the popular Florida Keys, as well as much of Miami-Dade County and other low-lying and coastal counties in the state. The mandatory evacuation order extends to more than 1 million Floridians and could be one of the largest evacuations in the state’s history, according to Miami-Dade County Mayor Carlos Gimenez.

Irma is expected to make landfall early Sunday morning, and Scott has ordered 7,000 National Guard members to assist with rescue and relief efforts.

“Obviously, Hurricane Irma continues to be a threat that is going to devastate the United States,” Brock Long, the head of the Federal Emergency Management Agency, said on Friday.
